I can't believe I've been looking for some answer to this for a week. It's like nobody understands on the 2008 body the mirrors swivel point gets loose. There is no screw to tighten. I swear I've read 12 forums and a half dozen comments in each where people are explaining how to tighten a screw. Lol It a rivet. It's a terrible design. Because there's no easy way to fix it. Your best bet is to think shims. Or get a washer that will fit but be tight. Cut it to make a slot for the rivet to pass throughIf your model is 2008+, there should be a little foam cushion covering the Allen bolt that allows the mirror to swivel back and forth. Remove that piece and put it on a surface where you won't get dust on the sticky surface. Get an Allen wrench and tighten it enough that you won't strip it. After that, replace the foam cushion and it should be fixed.
